Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The vulnerability is remotely reachable over the network without authentication (AV:N/PR:N/UI:N) against Joomla sites running AcyMailing versions before 10.11.1. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are moderately consistent toward high priority but with gaps. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a crafted HTTP request to a vulnerable AcyMailing endpoint on a Joomla site, embedding malicious SQL in a parameter that is concatenated into a database query. Because the vector is network-based and requires no authentication (PR:N), the attacker extracts subscriber data, Joomla user records, or session/credential material from the shared database. … |
| Remediation | Vendor-released patch: AcyMailing 10.11.1 - upgrade the extension to 10.11.1 or later, which resolves the SQL injection. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
24 hours: Identify all Joomla instances running AcyMailing versions prior to 10.11.1; disable the extension on systems unable to patch immediately; enable database query logging. …
